Simon Tatham is a hero A fantastic collection. All playable offline. Puzzles generated from customisable settings. All completely free with no adverts. Considerable documentation for each game. Simon Tatham is a hero here and the only thing missing is a "donate" button! Lots of credit also goes to Chris Boyle for this Android port.

Loved it! I've really enjoyed this up until today! Suddenly the colours are all changed, backgrounds all black. What has gone wrong? I really don't want to lose this one! ... Half hour later ... Really prompt help, thank you, it's just the night mode. All sorted!

Amazing collection, no fancy graphics and music, just great puzzles ad free. The best, there should be an option to give more than five stars. 'Guess' stopped working properly, gives always same answer and does not let you make your second move, can you fix please?

Thanks, this is news to me - could you try phone settings / Developer options / Pointer location (halfway down) & see if you can draw smoothly through that area? That should rule out a broken screen. If so, drop me an email, I'll send you links to some old versions and we can hopefully establish where the trouble started.
